Great work! Another great point for treadmill servicers! Please be aware....inside a treadmill lift motor, there is a small potentiometer or pot, that watches the "throw" or position of the lift screw, which relates to the treadmill incline. These lift motors have a sheath or "nut" on the screw that MUST be set properly at the ZERO degree mark of the deck, for proper operation from zero elevation to 12% or whatever it's uppermost incline is. This must be assembled correctly, or like in this case, that motor begins to "pinch" at one end of it's "throw" and the current will rise in the winding and blow a fuse, saving the lift from burning up. Nice job troubleshooting Thad!

it could be the belt sticking under foot on the slide plate
ask the sports shops if there is a lubricant that you can used under the belt
check to see if the belt is correctly adjusted

Try to RUN the software calibration for troubleshooting.
However test the elevation motor, Lube THE MOTOR : shaft +gear+adjust the small POT for increase performance. see the diagram attached.
God bless you

It sounds like you have a membrane issue. There are a number of different T9450 models and they all have slightly different consoles. You'll need your serial number to help pinpoint the parts you need. Your best bet is to go through the manufacturer (johnsonfit.com) and have them help you get the correct membrane and overlay.

Renee, Here is how to recalibrate the incline motor. Read all of it It will be good to keep.
Plug in your treadmill, do not stand on the walking belt. Hold down the "Stop" and "Speed +" key and insert the safety key or magnet, let go of the two keys. Now press "Stop" key once. This puts you into the level 2 of calibration. Press the "Speed +" key slowly until you see 85 on the console, (at this point the display is going to show the percentage of motor usage and also the actual walking belt speed) at 85% motor usage your top speed should be between 10 and 10.5 MPH or (of 12 and 12.5) depending on the treadmill. You must know your treadmills top speed. (Important the motor may be damaged if you set the maximum speed higher than the maximum speed that your treadmill is made for). If the speed is higher than 10.5 or 12.5 then you need to turn the potentiometer down to the correct level. If the speed it to low you need to turn the potentiometer higher. Once the speed is correct you are done calibrating the speed. Press the (-) speed key to lower the percentage to (0). Next press the incline (+) button, this will make the incline motor go all the way to the maximum incline and come all the way down to the level position. Then remove the safety key and the treadmill will reset into the normal manual mode, when you re-insert the safety key. Matt

.5 oz of Icon lubricant(can be purchased on ebay cheapest) applied to deck. Adjust the walkbelt, check drive belt tension, check amperage on motor no load and under load, calibrate the speed and incline. You can calibrate your treadmill by doing the following:
let's try to calibrate the speed

1. With the key off press the speed + and stop buttons at the same time and hold
2. place the key on and release the buttons
3. press the stop key once
4. press the speed up til it reaches 85
5. if your max speed is 10 mph then it should read about 9.8-10.2
6. If it is over or under we will need to adjust the speed potentiometer on the motor controller
7. to do this remove the motor hood and find the electronic board.
8. there will be a round adjustable pot on the board that you can place a small screwdriver in to adjust.
9. depending on if you need it to speed up or slow down is the direction you will need to turn it.
10. the goal is to get it to be about .1-.2 mph more then the max speed of the treadmill.
11. As long as it is in the range above it is performing ok.

now to calibrate the incline:
1. remove safety key
2. press and hold the speed+ and stop keys at the same time
3. Put the safety key in/on and release the keys
4. press stop once
5. hit the incline + arrow and let the incline go the whole way up and down

Enter the testing mode after switching the treadmill POWER ON by pushing first ‘SELECT’ and then ‘SPEED DOWN’ and hold buttons pressed simultaneously.
LED scanning mode for verifying display functionality Press ‘ENTER’ to scan DATA LINES to verify display functionality Press ‘ENTER’ to scan SACN LINES to verify display functionality Press ‘ENTER’ to scan LED’s to verify display functionality After pressing ‘ENTER’ the TIME window shows “test” and the keypad functionality can be tested (the value displayed changes when a button is being pressed) Press ‘ENTER’ to enter IO mode (TIME display shows lift motor potentiometer value, SPEED reads speed from speed sensor and DISTANCE shows heart rate pulse) Press ‘START’ to test lower board relay (a “click” sound) and then press ‘ELEVATION UP’ for 2 seconds to increase the elevation to 8%. Press ‘ELEVATION DOWN’ to decrease the elevation to minimum percentage 0% Press ‘SPEED UP’ to increase speed value and ‘SPEED DOWN’ toto decrease speed value. Press ‘ENTER’ to repeat above test or ‘SELECT’ and ‘ SPEED DOWN’ buttons simultaneously to return to the normal mode
The lift motor calibration is done manually by following the following steps: 1. Drive the lift motor to 0% from user interface (inclination display must be 0%) 2. Switch off the treadmill and unplug the power cable 3. Remove motor cover 4. Fold up the running deck 5. Loosen two screws (A) attaching the lift motor nut (B) to the incline frame 6. Adjust the lift motor nut (B) so that there is 9 mm (.358 in ) gap between the upper end of the nut and the lift motor frame Tighten the screws (A) and verify correct elevation by measuring Adjusting lift motor to 0% position 2.76in 12% position 9.646 in measurement taken from floor to bottom of motor compartment frame.
